I want to purchase these Amazon sites from someone and they did manage to send me earning reports but I'm sort of skeptical. So I asked the seller if I could run my affiliate ID for 24 hours to see if I got any clicks or conversions. The sites themselves are "autoblogs" and the seller told me he cannot predict where the traffic comes from, so this makes me a little more paranoid. Anyway, he allowed me to input my affiliate/tracking ID for 24 hours to see the click/conversions. I had to give him my Amazon Associate Access Key and Secret Access Key - both of which I just signed for after the seller told me it was needed for his WP-robot script. My question is.. should I be worried that I gave him my Access key & Secret access key? Is there anything he can do with them? Was it necessary to give it to him in the first place? Any feedback is appreciated.
